The formula of the ISO TX whey isolate is the only product in the world with a wide variety of amino acids and a broad range of nutrients in order to protect the muscles of the body, avoiding muscle loss and keeping the body from using muscle protein cells and impeding depletion. It is a whey isolate obtained through exchange ultrafiltration. We have used a method that uses ionically charged clay resins that retain the protein and separate it from other components of the whey. Chemical products are used to adjust the pH such as sodium hydroxide and hydrochloric acid. This produces the purest form of whey protein isolate, free from impurities such as lactose, minerals and fat. Zero aspartame.
